BOOT OR SHOE FINISHING JACK.

SPECIFICATION forming part of Letters Patent No. 353,449, dated November 30, 1886.

Application filed December 31, 1885. Serial No. 187,260. (No model.)

To aZZ whom it may concern.-

Be it known that I, MOSES HARRIMAN, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Boot or Shoe Finishing Jacks; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to new and useful improvements in finishing-jacks for holding a shoeor boot in'the operation of finishing the bottom of the same; and it consists, essen tially, of novel devices by which the shoe or boot is clamped from the outside, dispensing with the necessity of a last.

I carry out my invention as more fully hereinafter described, and more particularly pointed out in the claims;

In the drawings, Figure l is a side elevation of such a device. Fig. 2 is a similar view showing a boot in place. Fig. 3 is a vertical cross-section showing the clamps closed. Fig. 4. is a similar view showing the clamps open ready to receive the boot. Fig. 5 is a separate view of the clampopening device. Fig. 6 is a plan View.

As illustrated in the accompanying drawings, A represents a bench, upon which my improved finishing-jack is secured in any suitable manner--as, for instance, by bolts a.

B B represent any suitable frame-work for supporting the springs and clamps.

C 0 represent a series of clamps for engaging the counters of the boot, and D D represent clamps for engaging the upper.

E E represent a series of springs, located, respectively, to act against the clamps D D, and F F represent a series of springs acting upon the clamps G G, for clamping the counters of the body. I find it convenient to arrange these various springs E E F F to bear against the frame B B and the clamps, respectively. They may consist of coiled springs located upon a series of bars, G; but I would have it understood that I do not confine myself to any particular form of spring, nor to any particular arrangement thereof, as any form of springs may be employed to hold said clamps firmly in engagement with the boot,

and to permit their being opened for the reception of the boot. The clamps are spread apart by the upward or advance movement of the cam-spreaders H H.

I have found the formsoutlined in Fig. 5 to be very convenient, the upper .ends of the lowered, as shown in Fig. 3. One or more spreaders may be provided with shoulders, as

shown at h h, to limit the upward throw. By employing two or more the clamps may be more evenly opened, as the clamps O C are more extended than the clamps D D.

To operate the spreaders I prefer to employ a treadle, I, connected therewith by means of a connecting-rod, J, the construction being such that when the foot is applied to the treadle the spreaders will-be thrown upward, and vice versa.

The operation of the device will be understood. The operator presses upon the treadle with his foot, and thereby opens both sets of clamps. The boot is engaged as shown in Fig. 2, the clamps D D engaging the upper, andG C the counter. The foot is released, and the springs press the clamps firmly upon the boot and hold it securely for the operation of finishing. By clamping the boot from the outside the operation can be done much more quickly, while at the same time my improved device holds the boot much more firmly.

It is evident that the clamps might be held in engagement with the boot in various ways, and I would have it understood that I would not limit myself solely to the use of the springs for binding the clamps upon the boot, as any mechanism which will'accomplish this result is comprehended in the scope of my invention-as, for instance, a set of toggle-joints or wedges.

It will be seen that this device is adapted for use in finishing either boots or shoes. In the two cases it may be desirable to change the form of the clamps to correspond with the different uses but my improved j ack is adapted for use for both these purposes.

I have shown and described two. sets of clamps-one for engaging the counter and one for engaging the upper; but it is obvious that a single set of clamps orclamping-jaws might be used instead so shaped as to engage both the counter and upper, and I would distinctly have it understood that my invention contemplates such a construction.

While this device is adapted to hold a boot without a last, it may be desirable, if employed for finishing certain varieties of shoes, to use it with a last, and I would have it understood, that I contemplate such use, also, as coming within the scope of my invention.

Thejaws, as shown in Figs. 3, 4, and 5, are constructed with broadened faces to support the forward end of the boot or shoe, and, as shown in said figures, the jaws are also divided longitudinally.

What I claim is- 1. The combination, in a boot or shoe finishing jack, of clamping-jaws for engaging the boot or shoe from the exterior, with wedgeshaped Spreaders, substantially as described,

which in the upward or advance movement between thejaws act to spread said jaws apart, and means for forcing thejaws upon the boot or shoe when the spreaders are moved downward or withdrawn, as set forth.

2. In a finishingjack, the combination, with the clamping-jaws and their retracting mechanism, of the spreaders H H, having wedgeshaped upper ends and shoulders 7 h, substantially as described.

3. In a finishing-jack, the combination, with the clamping-jaws and their retracting mechanism, of the wedgeshaped spreaders H H, treadle I, and connecting-rod J, substantially as described.

4. In a finishing-jack, the combination of the table A, clamp-frame B, clamping-jaws O G D D, springs E E and F F, spreaders H H, and a treadle for actuating said spreaders, substantially as described.

5. The combination, in a boot or shoe finishing-jack, of clamping-jaws for engaging the counter of a boot or shoe, separate clampingjaws for engaging the upper of a boot or shoe from the exterior, means, substantially as described, for forcing said clamping-jaws upon the boot or shoe, and mechanism, substantially as described, for spreading each series of jaws simultaneously to locate the boot or shoe therein, substantially as described.

6. The combination, in a boot or shoe finishing jack, of clamping-jaws separated 1ongitudinally, and constructed to engage the counter or upper of a boot or shoe from the eXterior,and means for opening and closing said jaws, said jaws constructed with broadened upper faces at one end to support the forward part of a boot or shoe when engaged therewith, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

osns HARRIMAN.
